A chemical peel is a skin-resurfacing procedure in which a chemical solution is applied to skin to peel away the top layers. The skin that grows back after a chemical peel is smoother and younger looking. Chemical peels are used to treat wrinkles, skin discoloration and scars typically on the face. A chemical peel can be done alone or in combination with other cosmetic procedures. Chemical peels can be done at different depths light, medium or deep depending on your desired results.
